there is one ethernet connector on the rear of the computer. use this connector to connect the computer to a 10-mbps, 100-mbps, or 1000-mbps network. the following illustration shows an ethernet connector.

   

    connect a category 3, 4, or 5 unshielded twisted-pair (utp) cable to this connector. the 100base-tx and 1000base-t fast ethernet standards require category 5 or higher cabling.

    the ethernet connector has one led that indicates ethernet-link status. when this led is lit, it indicates that there is an active connection on the ethernet port. activity between the computer and the network is indicated by the ethernet transmit/receive activity leds on the front and rear of the computer (see “controls, leds, and connectors” on page 9).
